I hardly see why you need to know. Anyways, it wouldn&#39;t have been public by any means. Marius was born on January 13 (?) 1997, which was approximately 4 years from when his mom married CP Haakon. I&#39;d presume he was christened (if at all) in mid 1997.

Marius was christened. In the unauthorized biography about Mette-Marit there is a picture fom the christening.

Thank you for the article, Mandy.
It almost looks as if Marius would do a "Froilan-slip" But it can also be, that he just helps the other boy. And on the whole he looks much happier than at official Royal events (the baptism of Ingrid or the wedding of his mother)

The article only says, that Marius played with other kids, gave out programmes for the ceremony, when guests arrived at the church.
And the article further says that Marius father Morten got engaged with Celine in May during a holiday-trip to egypt.
